critical impact:

getvfsbynumber - not supported; use sysfs (CrUn30)

UN Impacts

Problem description

The getvfsbynumber function exists on Tru64 UNIX, but not on HP-UX. However, the sysfs function provides similar results.

The getvfsbynumber function returns the symbolic name for the virtual file system type identified by the typeno parameter.

Solution description

Use the sysfs function to achieve similar results.

The correct way for applications to get the virtual file system type name is to call sysfs. Note that sysfs may not behave exactly the same as getvfsbynumber. Review your code and the applicable manpages for more information.

New behavior

 #include < sys/fstyp.h >

int error, typeno; /* typno = a file system type index */
char name[FSTYPSZ]; /* buffer contains the returned  
                    a null-terminated file-system type identifier */
error = sysfs(GETFSTYP, typeno, name);
